Pool sharks, hustlers, whatever you call them, they were out playing eight-ball billiards in the smoky air of the Rusty Nail Tuesday as part of the first day of athletics in the Scott and White Texas Senior Games.Ten contestants demonstrated the arts of ricocheting the balls off the ends of the table to accomplish a desired shot and sinking two balls at once along with the discouragement of having a ball perch on the very edge of the pocket only to teeter there and not fall in.The event marks a return to the sport for Espy Leroy, a 62-year-old El Paso resident who won trophies in the sport from 1978-1982 before giving it up as a result of her job duties as an accountant.She resumed the activity this year and won her first round game Tuesday before being defeated in the second."I like it (billiards)," she said. "It's fun. It's just a fascinating game." by Jonathan Walburgh
